I have a beefy desktop I use as a Plex server and also for downloading shows and movies. Sometimes I use it for Nvidia Gamestream to the nvidia Shield boxes I have in my house. I have to wipe Windows 10 and reinstall it but I was considering using Windows Server 2019 due to all the issues I have with Android detecting my smb shares and such. However, a coworker is telling me that Server 2019 is terrible for gaming because it doesn't have DirectX, drivers can be different, and Steam might not even work on Server 2019. I admit I know absolutely nothing about this, and I was always under the impression that Server 2019 was just Windows 10 with a bunch of options added, like 10 Pro compared to 10 Home. On a scale of 1 to 10, how much of a dumbass am I? I'm guessing I should just stick with regular Windows 10?

I have a Windows 10 "gaming PC" in my basement that mainly exists to run Plex, but I also use it for the NVidia Gamestream feature of Geforce video cards where I can have games stream to the NVidia Shield TV and NVidia Shield Portable devices in my house (very useful since I can't really sit in front of a PC any more these days like I used to).

For whatever reason, a particular game I have is required to be ran in Administrator mode to work. Since it's not a Steam game, I had to manually add the EXE in Nvidia's control panel. Anyway, because this game requires Administrator privileges, it will never open up in Gamestream because it's waiting for the UAC prompt to be accepted. I have to remote into the computer every time and click "OK" to get the game to start (or run downstairs, hook up the keyboard, hook up the monitor, and then click "OK").

Is there some way to disable the UAC prompt for this single solitary EXE? I found a few guides online; one creates a shortcut for the EXE that bypasses UAC however this will not work for me because the Nvidia software does not permit adding shortcuts; it has to be an EXE.

There was another thing I saw recommended that required messing around with Task Scheduler but I tried it and it didn't work. Gave some error about the game not being able to function (the article warned me that a lot of programs are not compatible with that method).

Anyway, short of disabling UAC completely, is there a way in Windows 10 Pro to disable the UAC prompt on a single EXE so I can enjoy this game from the comfort of my toilet?

If you select Windows Explorer from the task manager's main (processes) view, it also gives you the option of restart instead of end task, which makes the process of fixing weird shell graphical glitches etc. much faster. If you have an Explorer window open it'll be listed under Apps upfront but even if not it's there under Windows processes. In details view it'll still do end task, though.

Thank you! I will do restart from now on.

Also, to get to the task manager directly, press Ctrl + Shift + Esc.

Killing and relaunching explorer.exe can also be handy when you're experiencing some shell issues.

Yeah for some reason, Task Manager was saying that Windows Explorer was using 70% of my i7 9700k's CPU :psyduck:

So I force closed it without realizing it was going to take the taskbar and start menu with it. I still have like a day's worth of work up so I didn't want to have to reboot to bring it back. This new trick is super handy; I never knew you could load stuff rom Task Manager!

I also have another small question that google isn't really helping with (maybe I am the only one that cares about this). It used to be, as of like 3 months ago, that if you right clicked "This PC" and chose properties, it would bring you to a standard WindowsNT-style properties window where you could do things like enter Device Manager, advanced system settings, etc. Like this:



As of a few months ago, right clicking This PC and choosing properties brings you to a Metro app.

I know you can access it via some wacky means (start, run, enter: explorer.exe shell:::{bb06c0e4-d293-4f75-8a90-cb05b6477eee}.) but is there any way to put it back into the "This PC", properties menu?

I've been living with a lot of the Metro UI changes but this one kind of annoys me a bit to be honest.

Uhhh, yeah technically there's a way.

The registry object for "This PC" / "My Computer" is at HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}, so you could add a new entry to the shell menu there that runs explorer.exe shell:::{bb06 etc. However that reg key is one of the ones that's got system protection, so forcing the rights to edit it is possibly not a great idea. (And I bet it's the type of thing that would get reverted by major updates.)


Honestly, what item do you use from that old system info panel that you need all the time? Device manager is the only thing I can imagine pulling up more than once in a blue moon, but that's instantly accessible on the start menu right-click.

Just force of habit from the past 20+ years any time I want to go to device manager.

It's not the end of the world but since I am never on a tablet and I never use my touch screen I really prefer the "see everything at once without scrolling" luxury of the non-metro windows is all.

edit: I never knew you could access device manager by right clicking the start menu! I'll just do that from now on. Thanks! :)

Hey all, my wife's Window's 10 laptop has been running very poorly the past few days. Opening a program takes forever, opening explorer windows often has to be forced closed, etc. I tried to run "DISM /Online /Cleanup-Image /ScanHealth" in both PowerShell and a command prompt, and both times it just sits there doing nothing.

I thought maybe something went wonky out of nowhere with her SSD so I ran the Samsung Magician software and this is what it said:



I'm no expert but that write speed is abysmal and could be causing this, right? I would imagine that number should be at least 10 times higher, right?

If so is this just the SSD dying on us, or could something else cause it (like an errant program running in the background that would also give results like this)?

The drive seems to pass all SMART tests just fine so I don't know what to think.

Out of curiosity, what is the temp. of the system? Could it be an obstructed fan and the system is thermal throttling?

Thanks for the reply! I don't think it's the controller because it's a ThinkPad with two SATA hard drives and the other drive (mechanical) has normal speeds for a mechanical drive.

The temps seem fine, thank you for the suggestion though.

The weird thing is I just enabled something called "RAPID mode" in Samsung Magician, and then rebooted. Now the computer is flying again, with no errors or lockups. I ran the test again and am getting 540/385 instead of 543/5.

But the weird thing is Samsung Magician is giving this error:



So the thing isn't even enabled, but it somehow fixed it? Unless the reboot somehow fixed the issue. Though that doesn't make sense either because 5 previous reboots (before turning RAPID on) didn't fix anything.

If it happens again, open performance monitor and move to the disks tab and look for poo poo flooding the drive with writes

Klyith posted:

RAPID uses system RAM memory as a drive cache, which means your drive appears to be crazy fast. This is just masking whatever problem is causing the abysmal write performance. While troubleshooting the drive, you should leave it off.

(Also IMO I would leave that off in general. Write caching in RAM means you have much more chance of data loss from power loss or hard crashes -- anything that got put in RAM but not written to the drive is gone.)


Errant program running in the background would show up on windows task manager. There's a column for disk activity. So if this is happening you can look at that (hit more detail if task manager is just a tiny list with no detail). If windows is trying to do an update in the background it can consume a lot of disk writes.


#1 - check that TRIM is enabled in windows. If TRIM is disabled, or the windows drive optimizer (what used to be defrag) has been disabled, and the SSD is never getting trimmed, it can have major performance impact especially with writes.

tldr The drive fills up with garbage data and has to use its own garbage collector to sort out where new writes can go. Trim is how the OS can tell the drive what is garbage that it can throw out right away.


#2 Was the SMART tests just the stuff in samsung magician, or another program too? You could download CrystalDiskInfo here to see the raw SMART info, just to see if the drive is reporting errors that magician thinks are not high enough to warrant a warning.

Thanks a ton! I wasn't aware of the disk writing thing in Task Manager even though I'm in Task Manager all the time. I appreciate the tip! I guess I never looked there before.

I'll disable RAPID. Trim is in fact enabled. I have no clue what caused this to rear its ugly head seemingly out of nowhere. The SMART test thing was from Magician, but I will check in another program too.

I actually can't even believe the computer even started with a write speed of 5mbps.

I just like having it where you can see everything at once instead of having to scroll forever like in the stock Win10 start menu. I can go right to a control panel item without even opening the actual control panel. Also there's a lot of times where I am looking for a program, but I literally don't know the name of the program, so being able to see everything at once is a lot faster.

And it's not like the stock Win10 start menu is completely gone, either. If I ever want to use it, I just press shift+win and it pops up.

Also chalk me up as one of those people who has varied results in the stock Win10 start menu's search function. When I want to turn on "Night light", I type in "night" and press enter and it's literally a 50/50 crapshoot as to whether it opens Night Light or Peggle Nights.

Is there any reason they're even doing this? I kinda understood it in the Windows 8 days when they were trying to hone in on the iPad's market share, but I think tablet PCs that require an interface like Metro were pretty much fads like netbooks and 3-d televisions.

I regard this as them playing the hand MS dealt them. They make it AGGRESSIVELY difficult to take back any amount of control over updates; if just tearing the whole update system out is the minimum effort required to get it to go away and quit re-enabling itself like spyware, people who feel strongly about it will do that instead of just changing to manually approving them like we could in 7.

There are definitely somewhat less nuclear ways to accomplish that than the script under discussion, but it's not surprising that it would neuter updates while it's doing other crazy surgery on OS components.

Group policy editor, Windows Update, Configure Automatic Updates, Enabled.

bing bang boom, windows won't update without your permission, you can have control.


I used option 3 for like a year and a half back when they didn't have a good option to prevent unauthorized reboots, and never had it reset or re-enable itself. Sometimes group policies do get reset when MS changes what the options are (or removes them from your edition), but you're manually controlling your updates, you're reading all the changelogs aren't you?

I used option 3 for a while but I sort of recently (like maybe a year ago) found a better alternative (in my opinion). Basically it simply renames the auto-reboot executable. You get all the updates, downloaded and installed automatically, with the only difference being it will never force reboot on you. Hell you even get that nice little Windows with the little red dot icon in your taskbar signaling a new update is installed and waiting for a reboot. But instead of hitting "remind me in 7 days" or whatever, you just reboot it whenever you are ready (which might even be less than 7 days). This is the guide if you are interested: https://www.joe0.com/2019/10/17/how-to-prevent-windows-10-auto-restart-new-instructions-oct-2019/

I've been using that method for over a year now and have had zero issues, it's never reverted, and I still get all my updates automatically. It just never reboots on me unless I physically click "start, reboot".

Remember when Windows 8 didn't even have a start button, just the "move the mouse in the bottom left corner to open the fullscreen tile menu" gesture?

I actually managed to never have used Windows 8 ever, like not even for a second. Not sure how I managed to avoid it (I am always helping friends and family and co-workers with their broken PCs; it's cool because people repay me in spades with stuff like car repairs and crap like that; hell one time I fixed a co-worker's computer, I refused money when he offered, then like 2 years later he ran new electrical wire around my entire house for free because he refused money back).

Anyway a few months ago a neighbor's computer was crapping itself and I determined it was the hard drive. His computer was on Windows Vista so I figured while I was replacing the dead hard drive, I would install Windows 10 on it. I couldn't, because the built-in graphics card did not have Windows 10 drivers (I tried everything and could not get it out of 640x480 mode). Then I installed Windows 7 and it installed fine but I forgot Windows 7 was EoL so I upgraded it to Windows 8, which was the last version of Windows to have drivers for his graphics card.

I was legitimately aghast at how bad it was. I had never used it before; only heard stories. Again, this was very recently (I wanna say May of 2020?) so it was definitely on the latest Windows 8 release. Even after installing OpenShell for him, I couldn't believe how many things were 100% full screen with no way to minimize them (that I could find). When I went to Windows Update on the computer, it literally took up the entire screen, with no minimize, maximize, or whatever the middle one is called on the top right. It was like one of those viruses that take up your whole screen in hopes of tricking people dumb enough to not know about ALT+F4.

The only way I could figure out how to "minimize" the screen was win+D; I don't even think alt+tab worked. It was so incredibly jarring that I can't believe they never fixed it for whatever recent revision of Win8 I was using.

Yeah this sucks because he's in pretty dire financial straits and on top of all that we just kind of enjoy the hilarity of keeping this PC alive, considering how many times we've fixed it since I first built it for him in like 2009 or something crazy like that.

Believe it or not, it was working fine with Windows 10, and for the type of stuff he's doing (paying bills, playing fantasy football, playing me online in Monopoly 95 from Westwood). So I would love to keep this thing running for a bunch of different reasons.

The power supply definitely was bad, because the fan on it wasn't even spinning. The computer would shut off about 10 seconds after turning it on. I ordered him a new PSU on ebay and when I plugged it in...it turned off again after 10 seconds. I couldn't believe it, because clearly the old PSU was dead, and the new one was working fine, but it still did that. Then I took out a stick of RAM and it stopped happening. I actually found 4GB (2 2GB sticks) of RAM in my basement that fit this motherboard, and the computer posts just fine. I don't get how the RAM caused it, because both original sticks work fine, just as long as they aren't both in at the same time. But it's not a bad RAM slot because it just accepted these two new sticks I found just fine!

I am running chkdsk which says it has 338 hours remaining. If I get Windows 10 to boot I am gonna test the CPU with some sort of program or something. Praying this old dog still works though! We would like to celebrate its 15 year anniversary if possible.

Sorry I did mean to boot, into repair haha.

I can't get it to boot because it just stays stuck at "Preparing Automatic Repair". It rightfully wants to repair because his computer improperly shut down like 20 times before bringing it to me. But now that it has a new PSU and new RAM, I just want the computer to attempt to boot normally without trying to fix anything because it's perpetually stuck in thinking it needs to repair, which it shouldn't since there's a new PSU and RAM in it (the computer is no longer powering off randomly on its own).


Khablam posted:

Something sounds broken.

My guess is his bad PSU fried a stick of RAM and corrupted his hard drive a little bit. Could be the CPU, but I don't think it's that just because it's been on for 3 hours now doing chkdsk and it hasn't powered off.

One minor annoyance I noticed with Macrium Reflect (I've been using it for years and never noticed this): it doesn't matter if the old image is small, the new drive has to be the same size or larger. So my friend's old HDD was a 640gb WD spinny drive, which I made an image of in Macrium. He bought a 512GB SSD drive. The Macrium image was only 92GB (he doesn't use that much stuff). I kept getting "not enough space" errors when trying to put the old image onto the new drive, even though he had more than enough room. Not the end of the world, but just a head's up to anyone who might do this in the future, hopefully this tidbit saves you some time.

Actually I just noticed some bulging caps on the motherboard!



The funny thing is it's only those green ones. Every other capacitor on the motherboard looks fine, except for the green ones. I guess they are some lovely brand?

He's lucky because I have a huge bag of capacitors from an arcade monitor repair I was going to do a while back and never bothered with.

Before I waste my afternoon doing this, would a couple bad caps cause Windows 10 to boot poorly?

Edit: by the way I am only assuming those caps are bad. Three look like they have rust on top and one looks like it's bulging, but there's no crud around the bottom of any of them.

Thanks for the replies! Unfortunately after watching two YouTube videos I'm still too dumb to figure out how to test caps with a multimeter (I have no idea what to turn the knobs to, something every video fails to address) so I'm just going to replace all the bulging ones.

Unfortunately they seem to be a pretty odd one because they are all 1800uF 6.3V and Amazon is out of stock on them for two weeks. Microcenter by me carries capacitors but none of that exact "size". I really miss Radio Shack sometimes.

Thanks for all the replies. Yep I am replacing all 7 of the green ones. And yep my multimeter does not have a capacitor setting. I'm a moron and didn't realize you need a different device for that.

That being said, I cannot believe what an absolute nightmare it is removing these capacitors. I have liquid flux, regular flux, a Hakko soldering station, a solder sucker, and even desoldering wick and I can't believe how impossible it is to remove these things even with all that. I always seem to get one leg off just fine but the other one refuses to get all the solder out of the hole so a piece of the leg won't budge. I legit spent three hours on one of them, only for a piece of the leg to still be stuck in the hole. I added a bunch of new solder too to make it easier to remove but nothing worked.

I just ordered a Hakko FR301 desoldering station for $245 on Amazon which apparently is a steal because the amount of aggravation and cursing was not worth it. I've desoldered the PPU off of an NES (which is supposed to be famously difficult) in a tenth of the time it took me to get one and a half capacitors off.

Hell one of the legs was so impossible to remove that I had to run a wire from the other side of the motherboard just so the new capacitor could get wired in.



I'm not doing that six more times.

I'm sure this Hakko thing is gonna zap em right off in seconds but man I can't believe how difficult this was. I soldered an HDMI port on my Dreamcast for chrissakes!

I'll let you all know in two or so days if the cap replacements fixed it :)

Thanks again for all the help.

Those layers will suck every bit of heat out of your soldering iron making it very difficult to desolder through-hole parts, particularly with desoldering wick. Modern lead-free solder also doesn't help here.

It can actually be advantageous to add leaded solder to the joints before you try to desolder the component. Even with a proper vacuum desoldering station this will help.

Wow thank you for the explanation. I thought I was going crazy.

I added the solder to the bottom part of the motherboard, where the capacitor legs barely show up. Is this what you're referring to? I don't think I'd be able to get solder on the other parts of the legs as there's really no room under the capacitor for the iron.

The funny thing too is I never really looked at what a capacitor is doing in general and I still kind of can't tell (I know they like store power or something). I was checking continuity and I noticed all these capacitors are kind of all just connected together on the same metal "plane". I actually don't even know why polarity matters! It looks like everything is just all connected to one common ground spot on the motherboard or something! (I know this is going well beyond the scope of the thread by the way!)

Sounds to me like that $245 got him a nice soldering station he can use for hobbies, he's helping a friend, it's fun for him, and he's learning things. OTOH, I lurk the obsolete tech thread a bunch and none of this strikes me as out of the ordinary.

Yeah it's exactly everything you just mentioned. Plus I needed a good desoldering tool anyway because like I previously mentioned, I have and own arcade cabinet monitors I want to fix.

The voltage converter that powers the cpu outputs little bursts of power, so capacitors are used to stabilize the voltage and average it out over a fraction of a second.

They are like batteries but much much faster to absorb and release power, and much much lower capacity.

The reason big capacitors care about polarity is pretty simple: they are made of very thin layers of very fragile substances, and it's cheaper to design the layers under the assumption that one side is always positive

Cool to know! Thank you! I am familiar with resistors and their purposes, it just seemed confusing that capacitors are all connected to one another and I couldn't figure out their exact purpose!

The amount of capacitance you need to smooth out a hundred watts is inherently bulky, so the choice is between a bunch of medium-size capacitors all connected together or some really big ones. Medium-size ones are easier to deal with, easier to hook up with lower total resistance, and they let you get better placement.

For argument's sake (and so I understand it better) what would happen if I removed these bulging caps and literally just bridged them? Of course I'm not going to do that. I'm just curious.

I doubt anyone cares but I figured I'd post a follow up, unfortunately replacing the bulging capacitors didn't fix his motherboard. In fact, with the bulging capacitors the computer would at least attempt to boot. After I replaced the caps I couldn't even get a video signal from the computer at all. So I managed to make it worse somehow haha

I definitely recommend the Hakko desolderer though. I didn't use it for the first two caps and it was a hellish nightmare. The other five came off like butter.

Just placed a bid on ebay for the identical motherboard. Looks like I am going to win it for like twenty five bucks. The model number is identical yet I noticed there's none of these caps on the board at all, so there appears to be a later revision or something with less sata ports and less lovely capacitors which is cool.

Replacing the motherboard is pretty much cheating at this point but it's still pretty fun to keep this dinosaur running. That's the one thing I always gave Microsoft a lot of credit for. Aside from the early release of Vista, Windows tends to work faster with newer releases. Unlike OSX which usually makes your computer run a little shittier with each OS update.

I bet you checked this, but are the new caps in the correct orientation? They're polarized and can only go one way.

Thanks a billion but yep I was aware. I'm guessing I might have fried something on the motherboard by leaving the soldering iron there too long. It was ridiculous pulling out the old caps before I got the desoldering iron so I probably just pulled on something on the motherboard too hard. Or this thing was just on its way out anyway. Thanks for checking though!

I had a PC running with an old dual core athlon 64 for years because I have a HP ScanJet 4c flatbed scanner from the mid 90s that uses SCSI. I couldn't seem to find a good PCI-E SCSI card or inexpensive SCSI adapter that would support the old SCSI interface better than the Adaptec AHA-2940AU I have in there. The caps were bad and it was a little power hungry so I eventually just found a sandy bridge board with a PCI slot on it as a replacement. It's running windows 7 32 bit to support the ancient HP software for the scanner but it works well. I'm debating a trial upgrade to windows 10 32 bit at some point, but I'll probably just image the disk first and revert if it doesn't handle the scsi card.

It's funny you say that because this motherboard actually has a parallel port and floppy drive connector. I swear it runs Windows 10 absolutely fine for what he uses it for. I think I saw a video once on YouTube of someone running Windows 10 on a 133mhz PC.

Speaking of updates, I got my friend's PC back up and running (replacement motherboard came yesterday) and I cannot for the life of me run an update on this thing.

I run Windows Update and it says he hasn't updated since October. So I check for updates, it downloads it, and begins to install it. Every single time it gets to 100% or whatever and the update fails with error code 0x800f0831.

I've tried every solution I see on Google. I manually downloaded the update using Update Assistant and it says "thank you for updating to the latest version" even though it's not.

I tried all the fun DISM repair commands and all that, still no dice. Anyone have any other ideas of what I could try? He's going to be stuck on an outdated version of Windows 10 forever if I don't figure this out.

Have you tried the media creation tool mentioned above? See if that tells you you have the latest version.

I'm gonna have to wipe out a thumb drive for that? That's honestly a huge inconvenience but I guess I'll give it a shot.

Once I create the thumb drive, how do I go about attempting to install an update from it?

Thank you. Just so I know I got this right, I am "upgrading" even though I am not really upgrading?

No that's actually a really good theory because his computer kept crashing like crazy, most likely from a faulty motherboard. And I just realized now the third DISM command failed, probably because of corrupt files due to the computer forcefully shutting down so many times.

I'm currently extracting the install.wim file from a Windows 10 disc to point DISM its way to see if that fixes the issues before going the install media route.

Yes, modern Windows is a lot better about doing in-place upgrades, and that's essentially what is happening.

OK so I did this and now it's "installing windows 10".

Is this what it was supposed to do? Is he going to lose anything like saved Chrome data or desktop shortcuts?
